The ratio between the number of molecules in 2 g of hydrogen and 32 g of oxygen is: [Atomic mass: H=1, o=16] 1. 1:2 2. 1:0.01 3. 1:1 4. 0.01:1

1:1 Reason Hydrogen (H2): Molecular mass of H2 = 2 g/mol Moles of H2 = = 1 mole Molecules = 1 × Avogadro’s number = 6.022 × 1023 Oxygen (O2): Molecular mass of O2 = 32 g/mol Moles of O2 = = 1 mole Molecules = 1 × Avogadro’s number = 6.022 × 1023 Hence the ratio is 1:1
